We provide any-to-any voice communication between Telekom customers and the customers of other carriers. You can choose between two connection variants and the bandwidths between 150 Mbit/s and 10 Gbit/s: 

With the Customer Connect interconnection connection variant, the handover takes place on your premises with an active network termination device as an optical interface. With the Customer Connect interconnection connection variant in co-location, the interconnection takes place in collocations. In this case, you implement your own site networking.

Our IP-based mobile communications interconnection lines enable the mobile communication between the customers of other carriers and those of Telekom. Internationally, all communications services are provided via an IP Exchange connection by Telekom Global Carrier.
